Procedure
A solution of the product from (b) (1.03 g, 3 mmol) and tetrakis (triphenylphosphine)palladium (0.3 g) in THF (70 ml) was installed under an atmosphere of carbon monoxide and heated to 50° C. Tributyltin hydride (0.96 g, 3.3 mmol) in THF (40 ml) was instilled by motor-driven syringe over 4.5 hours. After an additional 0.5 hours the mixture was stirred with 100 ml of 10% potassium fluoride solution for 15 minutes, then extracted twice with dichloromethane. The organic layers were dried over magnesium sulphate and evaporated to an orange solid.
